CHAPTER 6: ACTUAL VALUES STATUSG30 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL 6-96RTC SYNC SOURCE actual value is the time synchronizing source the relay is using at present. Possible sources are: Port 1PTP Clock, Port 2 PTP Clock, Port 3 PTP Clock, IRIG-B, Other, and None, where "Other" means any less precise source (SNTP,IEC 103, IEC 104, or DNP). An actual value displays when the relay includes the IEEE 1588 software option.The GRANDMASTER ID is the grandmasterIdentity code being received from the present PTP grandmaster, if any. When therelay is not using any PTP grandmaster, this actual value is zero. The grandmasterIdentity code is specified by PTP to beglobally unique, so one can always know which clock is grandmaster in a system with multiple grandmaster-capableclocks.ACCURACY is the estimated maximum time error at present in the RTC, considering the quality information imbedded in thereceived time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, orthat the error cannot be estimated.PORT 1…3 PTP STATE is the present state of the port’s PTP clock. The PTP clock state is:• Disabled is the port’s function setting is Disabled• No Signal if enabled but no signal from an active master has been found and selected• Calibrating if an active master has been selected but lock is not at present established• Synch’d (No Pdelay) if the port is synchronized, but the peer delay mechanism is non-operational• Synchronized if synchronizedPTP - IRIG-B DELTA is the time difference, measured in nanoseconds, between the fractional seconds portion of the timebeing received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared to IRIG-B time.6.3.15 Direct inputsACTUAL VALUES STATUS DIRECT INPUTS ACCURACY:999999999 nsRange: 0 to 999,999,999 ns PORT 1 PTP STATE:No SignalRange: Disabled, No Signal, Calibrating, Synch’d (NoPdelay), Synchronized PORT 2 PTP STATE:No SignalRange: Disabled, No Signal, Calibrating, Synch’d (NoPdelay), Synchronized PORT 3 PTP STATE:No SignalRange: Disabled, No Signal, Calibrating, Synch’d (NoPdelay), Synchronized PTP - IRIG-B DELTA:500000000 nsRange: -500,000,000 to +500,000,000 ns DIRECT INPUTS AVERATE MSG RETURNTIME CH1: 0 ms UNRETURNED MSGCOUNT CH1: 0 CRC FAIL COUNTCH1: 0 AVERAGE MSG RETURNTIME CH2: 0 ms UNRETURNED MSGCOUNT CH2: 0 CRC FAIL COUNTCH2: 0 DIRECT INPUT 1:On
